Natural air cooling, small in volume and attractive appearance

Advantage:

Comprehensive protection motor

Highly integrates protection functions of motor, so that the
design, installation is simpler, reliable, and make a machine to be
multi-function. If the input voltage is too high, too low
protection; lack of phase of the input and output , three-phase
imbalance protection; load over-current, overload, short circuit
protection.

Intelligent:

After the traditional soft-start settle orders of time and the
starting voltage value, no matter how light and heavy load, the
program will finish the progress of soft-start in accordance with
the order of setting time. And the caused unnecessary waste of the
equipment while a light load, such as some equipments do not allow
low-voltage start long time; While heavy load, the accumulation of
time causes the damage of the soft starter component.SJR2
completely avoid the artificial defects, it can use the way of
induction of the load to start the soft starter.

The appearance:

The design creates a beautiful appearance, and makes the mechanical
structure to become better. The pedestal, radiator and shell of
SJR2, were made by the aluminum alloy casting, and make a more
reasonable and effective solution to the soft starter power
component cooling problem; beautiful shell increases the overall
quality, and make people feel comfortable, noble, elegant soft
starter.

The design of circuit board:

Soft starter design

The general wiring of the main control board of the soft starter is
the upper and lower levels, and the wiring of the main control
board of SJR2 add to four. Therefore it reduces the volume and
increases the functions, increases the whole anti-interference
ability significantly, and more applicable to be used in different
environments.
